Never let it be said that Terrence Trammell shies away from a challenge. He’s established himself as one of the world’s best in both the sprints and the hurdles, and Friday, in the Garden, he’ll try to turn in an historic double at the Millrose Games.

The 25-year-old is the reigning national indoor champion at 60 meters, and won the 60-meter hurdles at the 2001 World Championship. He’ll try to win both races just 25 minutes apart Friday, the first man in memory to even attempt such a sweep at Millrose.

“It’s a challenge, but I feel that I’m able to compete well in both events, so I’d like to try my hand at it. [But] on this level you have a lot of high-caliber athletes, it’s not like doing it in college or high school,” said Trammell.

“Hopefully it won’t be that challenging to come back and run again. I know there’ll be a lot of adrenaline, so there’ll be fatigue after the first race, but hopefully I’ll be able to come back for the second.”

While no man has attempted a sweep like this at Millrose, Trammell has set a precedent.

In 2000 he won both events at the NCAA Indoor meet; the following February in Pocatello, Idaho, he won the hurdles in a personal-best 7.66, then took the dash in a then-world-leading 6.45. And all this was on just four hours of sleep because of canceled flights and a 17-hour trip.

He’ll have much better conditions Friday, and if all goes well he might consider trying to double at the national meet and even Olympic level, where the double would include the 100 meters and 110-meter hurdles.

“That’d be a pretty big challenge, although I’d like to sit and map things out. That’s something I’d like to do,” Trammell said. “I still have high aspirations of making the team in both events. Until it’s done everyone will feel it’s not probable. I think it can be done.”

When Trammell toes the line Friday, chances are he’ll be a crowd favorite. He hurdled 7.47 to break Greg Foster’s Millrose record two years ago, and runs that race this year Friday at 7:05 p.m. against defending champ Larry Wade and three-time champ Allen Johnson, Trammell’s training partner.

“It’s an advantage to train with somebody like Allen,” Trammell said. “The knowledge and the wisdom that he’s passed on to me over the years has been instrumental. Being able to line up next to him in practice, to share information back-and-forth, really helps us both.”

He’ll run the 60 meters at 7:30 p.m. against defending champ Shawn Crawford, world-indoor record holder Maurice Greene, Jon Drummond, and Justin Gatlin. And it was only serendipity that got him into this year’s race, after Great Britain’s Dwain Chambers dropped out.

At the USATF convention in December, Trammell’s sister/agent Kim broached the subject to meet director Howard Schmertz, who promised this opportunity. When Chambers entered the dash it overcrowded the field, but he pulled up lame last week in Florida, opening a space.

“I called Kim back and said Terrence is back in again, if he’s not too angry with me and wants to double,” Schmertz said. “It’ll be quite a feat if he pulls it off. Unless somebody breaks a world record, I’ll just hand him the [Outstanding Athlete] trophy right there.”
